My previous games used Java and LWJGL but I decided to make a big change and leave Java behind.

Superforce is written in C++.

When I started making games, I thought Java was a good choice. It is a nice language. I know it really well. The IDEs are super powerful and garbage collection usually doesn’t hurt too much.

But when the iPhone and the App Store appeared and started gaining momentum, Java left me out in the cold. First, I was just disappointed. Perhaps they would add Java support in a few months. But it didn’t happen. Disaster.

It wasn’t an easy decision to change my main technology. I took it very seriously. After completing two games, I had a lot of reusable code which seemed valuable. But I knew needed something solid that really does run everywhere.

So for Superforce, I quite literally started from scratch. Clicked Xcode > File > New Project and started rewriting my engine in C++.

Another piece of C++ code I wrote recently: a C++ wrapper for SQLite. Thanks to a few C++11 features I think it allows for really clean and concise code in many common cases. As part of the example code, I also wrote a basic schema migration function.

Don’t ask me why, but I needed a simple HTML template library for C++. I looked at a few of them, but there wasn’t a clear winner. Most were too heavyweight, hard to build or I didn’t like the syntax.

So I decided to write my own. How hard can it be?

NLTemplate is really simple. It comes in a single source file, has no extra dependencies and you can just drop it in your project and it will work. It does variable replacement, optional or repeatable blocks and file includes. You can define your own file loader to deal with path resolution and file I/O. To insert a variable, you write {{ variable }}, to define a block, you write {% block name %} and then end it with {% endblock %}.
